  • Apparatus to detect interference in wireless signals
    Patent number: 10784907
    Abstract: An apparatus to detect interference in wireless signals, comprising an antenna for receiving a wireless signal; and wherein the apparatus is operable to identify a dominant waveform in the received signal; subtract the dominant waveform from the received signal to create a modified received signal; and repeat the above steps, recursively substituting the modified received signal for the received signal, until all adjusted reference waveforms have been subtracted.
    Type: Grant
    Filed: February 13, 2017
    Date of Patent: September 22, 2020
    Assignee: ANRITSU COMPANY
    Inventors: Kee-dyi Huang, Bhaskar Thiagarajan, Randy L Lundquist, Vaidyanathan Venugopal

  • Method and apparatus to estimate wireless base station signal quality over the air
    Patent number: 8169993
    Abstract: The quality of the signal from a base station is measured and adjusted for distortion due to multipath and due to signals from neighboring co-channel base stations. The signal quality is measured conventionally by determining Rho or EVM and then Rho or EVM are adjusted.

  • METHOD TO DETECT INTERFERENCE IN WIRELESS SIGNALS
    Publication number: 20100105346
    Abstract: A method to detect interference in wireless signals, comprising sampling a received signal; identifying a dominant waveform in the received signal; subtracting the dominant waveform from the received signal to create a modified received signal; and repeating the above steps, recursively substituting the modified received signal for the received signal, until all adjusted reference waveforms have been subtracted.
